I don't know what a nitrate removal sponge is. I know of the sponge
filter with an air pump, but I thought that was just a cheaper
bio/mechanical filter, which still produces nitrates.

It's a replacement sponge for one of the sponges in your biofilter,
impregnated with AFAIK some kind of resin which reduces Nitrates.
Works for me, Nitrates are usually 5

I have to laugh at myself sometimes, so feel welcome to do so also. I had
to google to find out what 'some kind of resin' AFAIK was The sponge
sounds interesting. Not sure that I have seen. Would that be some sort of
Nitra Zorb sponge (which I have seen for Renas-dont have) or something a
little different. Not ammonia reducing sponge right?
